Simatic/TI 505 Ethernet Driver Help

Each device has now been defined under its own channel. In

this new configuration, a single path of execution is

dedicated to the task of gathering data from each device. If

the application has 100 or fewer devices, it can be optimized

exactly how it is shown here.

The performance will improve even if the application has

more than 100 devices. While 100 or fewer devices may be

ideal, the application will still benefit from additional

channels. Although by spreading the device load across all

channels will cause the server to move from device to device

again, it can now do so with far less devices to process on a

single channel.

Block size, which is available on each defined device, can also affect the Simatic / TI 505 Ethernet driver's

performance. Block Size refers to the number of bytes that may be requested from a device at one time. To refine

the performance of this driver, configure Block Size to one of the following settings: 32, 64, 128, or 250 bytes.

Depending on the Simatic / TI 505 Ethernet device model, the Block Size setting can affect the application's

performance drastically. A default value of 250 bytes is recommended. If an application has large requests for

consecutively ordered data, however, block size should be increased.
